Hi Ross

I also have this model, but my wing is still covered. However, I did stumble across this pc9 retract thread some time ago [link]http://www.rcuniverse.com/forum/m_3598534/mpage_4/key_/tm.htm[/link]. If you scroll to the bottom of the page, there are some images posted of the wings without the covering that may be of use to you. Check out the other pages in the thread as well, as there are more images scattered around the place. Not sure how much help these will be, but at least they will show you what it looks like.

Hope this helps
